Mr. Wollaston, who confesses it is apuzzler, admits that it has the aculeatum pinnule, and suggests that it may bea natural hybrid. Mr. Wills, writing with reference to it, says, I am inclinedto think it aculeatum, from its having a greater resemblance to it than toangulare,— rigidity, though the parts are slender, — sheen or gloss on uppersurface of pinnules,—shape of frond,—the same angle at parting from rachis,—pinna; also tending to diminish in length from middle of frond downwards, Mr. Fox adds that it has also the peculiar shade of green of angulare. ?.
